ID	Method	pH	Temperature	Details
1		6		FROM 2.63M SODIUM MALONATE, 0.1M BISTRIS PH 6.0, 0.24M NACL. CRYSTAL WAS CRYOPROTECTED BY 3.4M SODIUM MALONATE, 0.1M BISTRIS PH 6.0, 0.25M NACL. PHASES WERE DETERMINED BY SOAKING CRYSTAL IN 2.8M SODIUM MALONATE, 0.1M BISTRIS PH 6.0, 0.5M NABR FOR 1 MINUTE PRIOR TO CRYOPROTECTION.
